asp.net GridView绑定到数组，用数组绑定到<asp:GridView

前台:

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" AllowSorting="true"> 
    <Columns> 
        <asp:BoundField DataField="id12333" HeaderText="id"/> 
    </Columns> 
</asp:GridView>

后台：

protected void Page_Load(object sender, EventArgs e)
{
	if (!IsPostBack)
	{
		BindGridView();
	} 
}
void BindGridView()
{
	this.GridView1.DataSource = GetTable();
	this.GridView1.DataBind();
}
DataTable GetTable()
{
	DataTable dt = new DataTable();
	dt.Columns.Add("id12333", typeof(string));
	string[] str = new string[3];//把这个数组改成你的就好了 
	str[0] = "11111111";
	str[1] = "2222";
	str[2] = "3333";
	for (int i = 0; i < str.Length; i++)
	{
		str[i] = str[i].ToString();
	}
	for (int j = 0; j < str.Length; j++)
	{
		DataRow row = dt.NewRow();
		row["id12333"] = str[j];
		dt.Rows.Add(row);
	}
	return dt;
}

下边的例子是从数据库里取出值，把值用split分割后在转成数组的形式绑定到GridView

前台

<asp:GridView ID = "gvwQXLB"  AutoGenerateColumns = "False" Width = "100%" runat = "server" Height="100%">
    <Columns>
        <asp:TemplateField HeaderText="选择">
            <ItemTemplate>
                <asp:CheckBox ID="ckbYHQX" runat="server"  />
            </ItemTemplate>
        </asp:TemplateField>

        <asp:BoundField DataField="bodfViewYHQX_menucaption" HeaderText="用户权限"/> 

        <asp:BoundField DataField="bodfViewQXLB_qxlb" HeaderText="权限类别"/>   

    </Columns>
</asp:GridView>

后台

#region GridView绑定数据，显示用户权限

/// <summary>
/// GridView绑定数据，显示用户权限
/// </summary>
private void gvwBind()
{
	DataSet ds = new DataSet();
	DataTable dt = new DataTable();
	dt.Columns.Add("bodfViewYHQX_menucaption", typeof(string));
	dt.Columns.Add("bodfViewQXLB_qxlb", typeof(string));

	Model.userInfo.UserKey modelQXFP = new Model.userInfo.UserKey();
	BLL.userInfo.UserKey bllQXFP = new BLL.userInfo.UserKey();

	string yhmc;
	yhmc = Request.QueryString["yhmc"];

	ds = (DataSet)bllQXFP.get_YHQXXX(yhmc);

	string[] bodfViewYHQX_menucaption = new string[ds.Tables["dzjc.dzjc_yhqx"].Rows.Count];//开辟数组空间
	string[] bodfViewQXLB_qxlb = new string[ds.Tables["dzjc.dzjc_yhqx"].Rows.Count];
for (int i = 0; i < ds.Tables["dzjc.dzjc_yhqx"].Rows.Count; i++)
	{
		bodfViewYHQX_menucaption = bllQXFP.get_YHQXXX(yhmc).Tables["dzjc.dzjc_yhqx"].Rows[i]["MENUCAPTION"].ToString().Split(',');//MENUCAPTION中数据格式个，“aa,bb,ccc,d,eeee,”
		bodfViewQXLB_qxlb[i] = Convert.ToString(bllQXFP.get_YHQXXX(yhmc).Tables["dzjc.dzjc_yhqx"].Rows[i]["qxlb"]);
	}

	for (int j = 0; j < bodfViewYHQX_menucaption.Length - 1; j++)//获得bodfViewYHQX_menucaption数组长度减一，因为MENUCAPTION中数据存储格式为“aa,bb,ccc,d,eeee,”，最后一个字符为“,”，所以要给长度减一
	{
		DataRow row = dt.NewRow();
		row["bodfViewYHQX_menucaption"] = bodfViewYHQX_menucaption[j];//把分割出来放到数组里的字符串放到DataRow里
		row["bodfViewQXLB_qxlb"] = bodfViewQXLB_qxlb[0];//同一个用户的权限类别相同，所以取下标为0的数组
		dt.Rows.Add(row);
	}

	gvwQXLB.DataSource = dt;//绑定到数组
	gvwQXLB.DataBind();
	ds.Dispose();
}
